I have maas installed on a single ubuntu 18.04, I have one domain that is being managed with maas dns. I made a mistake the other day adding an entry and can’t remove it.

Essentially I have a domain like: home.{domain}.com being managed by maas.
I mistakenly added an A entry of: ad.home.{domain>}.com which translated to: ad.home..com.home.{domain}.com
When I try to remove it in the GUI no errors, just doesn’t remove it. In journalctl there is this entry that coincides with trying to remove the entry:

You should be able to delete the dnsresource from the command line using the dnsresource id.

Once you have logged in to MAAS on the command line you should be able to run maas SESSION dnsresources read to list all the dnsresources with their ids and then run maas SESSION dnsresource delete ID to delete your unwanted dnsresource.
